Before you start, please unzip hijackthis to a separate folder. The program will make backups in the folder in the folder it's in.
These easily get lost in a Temp folder or in the root of C: or get scattered all over the desktop and we need to empty the temp folders to remove the hijackers

Run hijackthis, tick these entries listed below and ONLY these entries, double check to make sure, then make sure all browser & email windows are closed and press fix checked

Reboot into safe mode by following instructions here: http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406
then as some of the files or folders you need to delete may be hidden do this:
Open Windows Explorer & Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and untick "hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"

C:\windows\temp and select EVERYTHING in it except temporary internet files, cookies and history folders and delete all that
then
1) Open Control Panel
2) Click on Internet Options
3) On the General Tab, in the middle of the screen, click on Delete Files
4) You may also want to check the box "Delete all offline content"
5) Click on OK and wait for the hourglass icon to stop after it deletes the temporary internet files
6) You can now click on Delete Cookies and click OK to delete cookies that websites have placed on your hard drive
